Linked scan at constant E2/V

This may be performed with a sector instrument incorporating at least one electric sector plus one magnetic sector. The electric sector field, E, and the accelerating voltage, V, are scanned simultaneously so as to maintain E 2/V ratio at constant value equal to the value of this ratio that transmits the main beam ions through the electric sector. The magnetic sector field is set at a fixed value such that main-beam ions of a predetermined mass/charge ratio are transmitted by the magnetic sector; these preselected main-beam ions are the precursor ions whose fragment ion spectrum is required. The fragmentation reactions thus observed occur in a field-free region traversed before the two sectors scanned in this way. The term E 2/V linked scan is not recommmended.
